CARL L. DORER, or BELLAIRE, OHIQ. APPARATUS FOR 'FIRI; FINISVHING Amp POL SHING. GLLAS\SWA RE.I

To all whom/it may concern.-

Be it known that I, CARL L. DORER, a citizen of the United States of America, and a county of Belmont, and State of Ohio ,"have invented certain new and useful Improvements in Apparatus for Fire Finishing and Polishing Glassware, of-which the following'is a specification. I

My invention relates to new and useful improvements in apparatus for fire polishing and finishing glassware; andit consists in the partlcular construction, arran ement, and combination of parts, which wi l hereinafter be fully'described.

The object of the invention is to rovide a simple and efficient. machine where y articles of glassware are -automatically fire finished and polished at one operation.

A further object is to providea machine the capacity of whichfor finishing and polishing articles of glassware is not only very much. in excess of that of prevailing devices, but whichpossesses many advantages over said prevaihng devices, some of which Will hereinafter be made ap arent; and astill further object is to provld ea conveyer by means of which the articles transported from a point convenient to the presses to a point near theannealing-leers.

With the rotating type Offinishing-machines which is in more or less common use the centrifugal action of the machine tends to flare the heated articles which are carried Itherebyon the outer sides, thus giving the articles alop-sided a pearance. This obe present device, since are thereby carried in a straight In describing the invention in detail reference is herein had to the accompanying va part of specifica- Flgure '1 is a side elevation of the invention.

verse shafts 5, each of which carries a centrally-located s rocket-wheel 6 fast thereon,

said sprocketeels being endless s rocket-chain at one en the girders 1 as to be 7. The bearings 3 connected byan of the machine are so attachedito longitudinall adjust-l able, the purpose being to provi e means whereby the tension of the chain may be adjusted. While various meansfmay be. em

ployed'for this purpose, I prefer tolempl'oy ongitudinally-movable eXte between the shoulders 3 .of end of the I girder 1 a suitablewedge 3 may be driven.

.' Carried by'saidv chains 7- isv a.

plurality of holders 8, on whichthe articles of glassware are carried. This holder carries narms 3 llilich and-the a receiver 9, which may beof-any size. or. I

shape're'quisite for holding. the article of glassware to be finished, a cup-shaped receiver being shown in thepresent instance I for receiving or holding tumblers and the like. Said holder 8 consists of. a broad base plate 10, which is rigidly secured to a link of the chain 7 in a suitable manner, -a boxplate 11, carried by'said base-plate, a revolu-" 1e. spindle 12, vertically mounted at its lower end in said base-plate and projecting through the horizontal portion-of said box;v

plate, and said receiver 9, the latter having in which-the 1113- per end of the Rigidly mounted the base-plate 10 and the orizontal ortion of the box-plate 11, is a small'cogw eel or pinion 14, which is ada ed at a suitable point, as will hereinafter be explained, for rotating said s indle andthe receiver'which is carried thereby.

A trackis formed by two 0 positely-disposed angle-bars 16, over whic the forward spindle 12 is rigidlyjheld on's'aid spxindle 12,b'etween ted to engage a.-'

traveling portion of'the machine travels, the

chain 7 being carried between the adjacent edges of the two angle-bars, while the under faces of the base-plates 10 on opposite sides of the chain slide upon the horizontal portions of said angle bars, this construction ular travel providin for the smooth and re of theho ders 8, bearing the, artic es of glass' ware. 'A"'sec'ond or return track is formed for carrying the returning: portion of the ch in 7,-said track comprising two "oppositely-disposed an le-bars 17 ,on the horizontal portions of w faces ofthe u turned "base-plates 10on' ope posite sides oi ich slide the then under IIO the pinion 14, while the pori tion of the holders 8 carried by said baseplates depend therefrom and travel between the adjacent edges of the two angle-bars 17. The ends of each of said angle-bars 16 and '17 are split, and the vertical sides thereof are turned or flared outward and the horizontal sides thereof are turned downward, thus providing guides for properly directing the baseplates as they enter upon and leave the said tracks.

The angle-bars 16 are supported upon two or more cylindrical bodies 18, which are e0- centrically mounted on shafts 19, having their ends journaled in the opposite irders 1, as shown. The verticalsides of said anglebars abut against annular shoulders or flanges 20, provided at the ends of said cylindrical bodies 18 and, as is apparent, by turning the shaft 19 the hei ht at which the holders travel in passing orward through said machine may be readily adjusted. Adjusting-nuts 21 are provided on said shafts 19, by means of which the latter may be secured in any desired position.

As driving mechanism for said machine a small motor 22 is mounted upon a suitable support, as 23, which stands upon the frame, the pinion 24 on the motor-shaft 25 meshing with a gear-wheel 26, provided upon the end of a shaft 27, which has a perpetual screw or worm 28 thereon, which acts upon the teeth of a wheel 29, fast upon a suitably-mounted transverse shaft 30, communicating a rotary motion thereto. A sprocket-wheel 3 1 is also mounted on said shaft 30, said wheel being connected by a sprocket-chain 32 with a sprocket-wheel 33, which is mounted on a transverse shaft 34, journaled in the opposite girders 1 of the frame. Mounted in a suitable osition on said shaft 34 is a second sproc et-wheel 35, which is connected by a I sprocket-chain 36 with a sprocket-wheel 37,

rovided on the shaft 5 at the rear end of the ame.

While I have described more or less particularlyta. gearing suitable for driving the machine, it will be understood that this is but one of a variety of methods or ways in which the machine maybe geared. Therefore it will be noted that I do not wish to limit myself to the gearing mechanism herein described, it being merely employed herein in order to show an 0 erative mechanism.

Located on the ame at a suitable oint,

referably near the'front end thereo is a urnace 38, consisting in part of side walls 39 of brick, fire-clay, or other suitable material,

mounted upon laterallyadjustable angleplates 40, located at each side of the path of travel of .the chain 7 and ware-holders 8, and of a cover or dome 41, mounted on said side walls 39. Said side walls 39 are each formed with a horizontal. or substantially horizontal ledge 42 on their inner faces,,and entering the furnace through the dome 41 directly over the horizontal ledges 42 are each adapted for directing a ame against the ledge 42. Said gas-pipes 43 lead from a large gas-pipe 44, which serves as a reservoir for containing a reserve gas-pressure, whereby a steady flow of gas to said pipes 43 is provided for. At a point above the dome 41 said gas-pipes enter air-blast pipes 45, which are connected with a large air-conductor 46. Said air-pipes entering the furnace together with the gas-pipes direct the flames from the burnin gas in the form of a blast against the faces 0 the ledges 42, from which said flame is horizontally deflected over the tops of the articles of glassware which are being carried through the furnace, reheating said articles without the flames coming into actual contact therewith. Thus the roughand uneven edges carried by the ware after leaving the molds or presses are melted down, so that the ware after passing through said furnace presents a perfectly-true smooth edge. This reheating further imparts to the ware a rare luster and brilliancy.

. Attached to the vertical portion of one of the angle-bars 16 and extending from one end of the furnace 38 to the other is the toothed rack 15, which is adapted to be enas-pipes 43,

gaged by the inion 14 of the holders 8 to rov lugs 47, which are slidable upon lateral arms 48, secured to the outer faces of the girders 1. A bolt 49, carried by each lug 47, is slidable in a slot 50, provided in the arm 48. The walls of the furnace may be adjusted relatively to each other to adapt it for the passage therethrough of articles of glassware of different sizes by the manipulation of the parts ust' described.

The general operation of the apparatusis as follows: The articles of ware immediately after being formed in the presses are placed one at a time u on the holders 8 at the front end of the mac ine. Said holders are being carried by the traveling chain 7 at a regular and uniform rate of speed. Hence while still hot from the press the said articles are carried into and through the furnace, being therein subjected to the intense heat of the fireblasts which are deflected by the ledges 42 over the tops of the articles of ware without actually coming into contact therewith. The rough edges of the ware are fused, formin a perfectly smooth and even surface or e ge upon the articles, and at the same time the ware is polished from contact with said heat. In passing through the furnace the holders bearing the ware are rotated, thus rotating the ware, so that all sides thereof are subjectedtothesame degree of heat. Having 1 passed thr ough the furnace, the ware is con- 7 veyed'to the op ositeen'd of the machine,

which is prefera ly located at a point convenient to th'e annealing-leers, where the articles are one by one removed from the holder It wi llbenoted that th u 4 I erval or space b tween adj acent holdersB iss'mall, and since the chain'carrying said holders travels constantly at auniformrapid rate of sp eed the capacity I ishing' glassware, a longitudinal frame, a

ofthe machine or apparatus is very great.

Various changes or alterations maybe re,- sorted towithout departing from the general spirit or scope of the invention. Hence I do not desire to limit myself tothe-precise construction- 'and' arrangement of parts herein shown and describe I What I claim as new, and desire to secure by Letters Patent, is I '1.
